srncrrrenrron forming part of Letters Patent No. 657,215, dated september 4, ieoo. Application filed August 25,1899. Serial No. 728,477. (No model.)

To @ZZ whom t 7a2/ay concern:

Beit known that we, GEORGE ALBERT FAR- RALL and CHRISTIAN MAUL, citizens of the United States, residing at Batavia, in the county of Genesee and State of New York, have invented new and useful Improvements in Oorn-I-Iarvesters, of which the following is a specification.

This invent-ion relates to a corn-harvester of the general type which is shown and described in Letters Patent of the UnitedStates granted to the Johnston Harvester Company, No. 603,759, dated May l0, 1898.

The objec't of the present invention is to improve this type of harvesters in several respects.

The harvester referred to contains a platform which is arranged lengthwise to the line of draft and which is mainly upright but inclines stubbleward, so that its bearing-surface faces grainward and upward. A binderdeck extends stubbleward from the rear end of the platform and conveyer-belts run along the platform and binder-deck. These belts are provided with pivoted teeth, which fold back in running along the binder-deck when they are not required to convey stalks, and the position of the teeth, whether projecting or folded bacl ,is controlled by a pivoted guide arranged in the binder-deck.

One object of our invention is to improve the construction and arrangement of this guide and of the mechanism by which it is shifted or swung on its pivot from one position to the other, so as to render these parts strong and rigid and enable the guide to be easily shifted and to be securely held in position against the pressure of the teeth.

Another object of our invention is to improve aud simplify the construction of the means by which the binding mechanism is actuated, so that it is rendered compact and can be arranged higher than formerly in the machine, whereby clogging of the mechanism by foreign matter is avoided.

Another object of our invention is to improve the devices for adjusting the breastplate at the stubbleward end of the binderdeck.

Other objects of our invention are to improve the cutter mechanism by providing it with guiding and antifriction devices and to improve the means by which the bottom of the throat or stalk-passage is raised and lowered.

In the accompanying drawings, consisting of three sheets, Figure 1 is a side elevation of our improved harvester viewed from the grainward side. Fig. 2 is a fragmentary side elevation thereof viewed from the stubbleward side. Fig. 3 is a horizontal section of the harvester, taken substantially in line 3 3, Fig. 1, and showing the binder-needle retracted and the adjacent feeding-teeth in an operative position. Fig. t is a similar view showing the binder-needle projected and the adjacent feeding-teeth folded into an inoperative position. Fig. 5 is a fragmentary horizontal section, on an enlarged scale, of the crank and connecting-rod whereby the feeding-teeth guides are operated and showing the position of these parts when the guides are in their operative position. Fig. 6 is a similar View showing the position of the same parts when the guides are in their inoperative position. Fig. 7 is a horizontal section, on an enlarged scale, in line 7 7, Fig. 1. Fig. 8 is a horizontal section, on an enlarged scale, of the binderdriving mechanism in line 8 S, Fig. l, and showing the position of the parts when the binder mechanism is not in operation. Fig. 9 is a similar view showing the position of the parts when the binder mechanism is in operation. Fig. 10is a fragmentarysectional elevation in line 10 10, Fig. 8. Fig. 11 is an end view of the binder trip-lever and its actuating rod or bar. Fig. 12 is a fragmentary top plan view, on an enlarged scale, of the cutter mechanism. Fig. 13 is a horizontal section of the same. Figs. 14 and 15 are vertical sections of the cutter mechanism taken in lines 14 14 and 15 15, Fig. 12, respectively.

Like letters of reference refer to like parts in the several figures.

. A represents the main frame of the harvester, which is supported on the grainward side by a supporting-wheel et and on its stubbleward side by a driving-wheel o.

B represents the cutter mechanism whereby i the cornstalks are cut off and which is ar- ICO pass through the throat.

ranged on the lower portion of Vthe main frame. This cutter, Figs. 1, 3 and 12 to 15, consists,essentially, of a transversely-reciprocating cutter-bar b, provided with knife sections or blades b', a transverse finger-bar C, arranged in rear of the cutter-bar,and fingers or guards c c', projecting forwardly from the linger-bar and cooperating with the blades of the cutter-bar. v

In order to permit the cutter to work easy, the same is provided with antifriction-rollers d d, which are mounted on the inner and outer ends of the cutter-bar and bear against the front side of the finger-bar, as represented in Figs. 12 to 15. Each of these rollers is pivoted to the under side of a guard cap or plate d2, which is secured to the top of the cutterbar and projects rearwardly over the fingerbar, as shown in Figs. 12 and 14, so as to prevent any obstruction from entering between the roller and the finger-bar and clogging the same. The front part of each cap extends underneath the overhanging part da of the adjacent side guard or finger c and is guided thereon by cooperating guide-faces d4 d5, arranged, respectively, on these parts. The cutter-bar may be reciprocated in any suitable or well-known manner-for instance, by means of a pitman c3, connected at one end with the cutter-bar and at its opposite end to a crank c4 on a shaft c5, as shown partly in Fig. 3 and partly in Fig. 12.

E represents the inclined conveyer-platform, which is arranged lengthwise on the main frame with its lower portion adjacent to the stubbleward side of the cutter and which leans toward the driving-Wheel.

E represents the inclined binderdeck, which extends rearwardly and stubbleward frointhe rear end of the platform. The platform and deck form the stubbleward side of the throat or passage through which the stalks pass. The grainward side of this throat or passage consists principally of three guide-bars F F F2, which extend lengthwise of the platform and are supported on the main frame by standards ff'.

G represents the bottom of the throat, upon which the butt-ends of the stalks rest as they This bottom extends from the rear side of the cutter along the lower portions of the platform and the binder-deck and bears loosely with its inner or stubbleward edge against the platform and binder-deck, While its outer edge is provided with an upwardlyprojecting guard-rim g, which confines the butts ofthe stalks on the bottom. The latter is capable of vertical adj ustmcnt to suit different lengths of stalks. For this purpose the bottom is made up of a number of pivotally-connected sections g' g2 g3 g4. The first or front section g is stationary and secured to the frame in rear of the cutter, the second section g2 extends along the platform, the third section g3` is curved to conform to the adjacent curved corner at the junction of the platform and deck, and

the fourth section g4 extends alon g the binderdeck. The middle part of the bottom is adjustably supported by a bracket g5, secured to the second bottom section and connected with the adjacent standard f by a bolt g, passing through a vertical slot in the bracket, as shown in Fig. 1.

H is an upright shifting rod arranged in rear of the deck and provided at its lower end with a curved arm h, which extends underneath the lower edge of the deck and upwardly to the throat-bottom, to which latter the arm is pivotally connected. Upon raising or lowering the shifting rod the rear part of the throatbottom is raised or lowered. The shifting rod is guided in lugs h', arranged 'on the adjacent stationary part of the machine, and the rod is raised and lowered by a 1 hand-lever h2, which is pivoted on the main frame and connected with its rear arm to the upper end of the shifting rod, while its front y arm extends toa point in convenient reach of the driver. The rear part of the throatbottom is held in its adjusted position by vany suitable device, which is controlled by the driver-for instance, a segment h3 and I a catch h4, which is mounted on the lever h2.

The front part of the throat-bottom is stationary, as stated. The middle part is ver- 1 tically adjusted by adjusting the bracket gfj to suit the average length of stalks which are being cut and is secured in this position. The position of the rear part of the throat-bottom is controlled by the driver, and this part is raised or lowered as the cutting progresses to j suit the varying lengths of the stalks, so that all bundles are tied approximately in the middle by the binder mechanism.

I I I2 represent conveyer or feed belts whereby the stalks are carried through the f throat to the binder mechanism. These belts are arranged lengthwise-of the platform and binder-deck, and each belt passes with its receiving portion varound a guide roller j, thence through an opening inthe platform and rearwardly along a guide j on the bearing side of the platform, thence rearwardly and stubbleward around a sprocket-wheelj, thence rearwardly through a slot js in the binder-deck, and thence forwardly around a delivery sprocket-wheelj4 to the place of beginning. Each of the guide-rollersj is journaled in a bracket secured to the platform. The intermediate sprocket-wheelsj2 of the several feed-belts are secured to an upright shaft The delivery sprocket-wheels ,i4 of the lower and intermediate feed-belts I I are mounted on an upright shaftj, and the delivery sprocket-wheel l7'4 of the upper feed-belt is mounted on a separate shaft j7, which is arranged axially in line with the lower shaft je. The feed-belts may be driven from the driving-wheel in the same manner as in the patent heretofore referred to. Each of the feed-belts is provided at intervals with feeding teeth or fin gers K, which project laterally therefrom into the throat or stalk-passage ICO IOS

when in their operative position. The inner end of each tooth is pivoted to a feed-belt and is provided with two trailing guide-shoes Za', which project backwardly at right angles to the tooth and straddle the feed-belt. As the teeth move along the bearing side of the platform their shoes engage with the bottom of the guides j and hold the teeth at right angles to the platform, in which position the teeth carry the stalks through the throat.

L represents movable guide-bars whereby the teeth on the delivery part of the feedbelts are held either in their operative position for feeding the stalks to the binder mechanism or are permitted to fold backwardly against the feed-belt into an inoperative position, so as to check the feeding action of the belts while the binder mechanism is tying a band around abundle. These guide-bars are arranged in pairs on opposite sides of the delivery part of each belt in the adjacent slot js and extend from the rear part of the platform rearwardly, thence st-ubbleward in a curve adjacent to the intermediate sprocketwheels, and thence obliquely to the delivery sprocket -wheels The front ends of the guide-bars are connected to an upright rockshaft Z. In the operative position of the guide-bars the same are swung forward into the slots J3, so as to be arranged close to the feed-belts, as represented in Fig. 3. in this position the shoes of the feeding-teeth engage with the guide-bars and are held parallel with the belts, whereby the teeth are caused to project from the deck and feed the stalkstothebindermechanism. Uponswinging the guide-bars backwardly from the feedbelts, as represented in Fig. at, the support for the shoes is removed, which causes the teeth to be folded backwardly against the feed-belts into an inoperative position, as shown in Fig. 4, whereby the feed of stalks is checked.

Z is an upright rock-shaft, which is journaled on the deck between the intermediate and delivery sprocket-wheels and which is provided with a number of shifting arms or cams Z2, by which the position of the guidebars is controlled.

In the operative position of the guide-bars the rock-shaft Z' is turned forwardly, so that its shifting arms bear squarely against the back of the guide-bars, near the free ends thereof, as represented in Fig. 3, whereby the feeding-teeth passing along the deck are held in an operative position. Upon turning the rock-shaft Z baekwardly in the direction of the arrow, Fig. 3, the shifting arms are swung away from the guide-bars and permit the latter to recede from the feed-belts, thereby causing the feeding-teeth to fold back into an inoperative position, as shown in Fig. 4.

M represents the binder-needle, which is arranged under the binder-deck and which passes at intervals through a slot in the deck and cooperates with the knotter mechanism N, arranged on the opposite side of the stalkthroat for tying a band around the bundle. The knotter mechanism may be of any suitable construction, and therefore only the cams 'n n of the same are shown for the purpose of locating the knottermechanism. The binder-needle is mounted on the upper end of a rock-shaft M', which is journaled in bearings behind the deck.

m represents a connecting-bar pivoted at one end to a crank m on the needle and provided at its inner end with a slot m2.

'm3 is an actuating rock-arm which is secured to the rock-shaft Z and provided at its free end with a bifurcation which receives the slotted end of the connecting-bar and which is provided with a pin 'm4, passing through the slot thereof. In the retracted or inoperative position of the needle 'the connecting-bar pivoted thereto engages the outer end of its slot with the pin of the bifurcated rock-arm m3 .and turns the latter, together with the rock-shaft Z' and the shifting arms connected therewith, so that the latter hold the guide-bars and the feeding-teeth in an operative position, as shown in Figs. 3 and 5. As the needle begins to move forward across the throat for tying a bundle the outer end of the connecting-bar engages with the shoulder or abutment m5 at the back of the bifurcated arm m3 and turns the same in the direction of the arrow, Fig. 3, until the outer end of the connecting-bar clears the shoulder m5, whereby the rock-shaft Z is turned so that its shifting arms are retracted and permit the guide-bars and feeding-teeth to move into an inoperative position, as shown in Fig. et. After the connecting-bar has cleared the shoulder of the bifurcated rock-arm the continued or last part of the forward movement of the needle causes the connecting-bar to slide with its slot on the pin m4 until it reaches the end of its forward movement, as represented in Figs. 1l and 6, during which movement the rock-shaft Z and connecting parts are not moved. During the first part of the subsequent backward movement of the needle the connecting-bar slides idly on the pin m4 until the outer end of the slot in said bar engages with the pin, after which the connecting-bar during the last part of its backward movement with the needle shifts the bifurcated rock-arm, together with the shaft Z/ and shifting arms Z2, so as to move the guidebars and the feeding-teeth into an operative position. During the last part of the outward movement of the connecting-bar its inner end is swung opposite the shoulder m5 of the rock-arm preparatory to shifting the same during the next inward movement of the connecting-bar.

In the above-described mechanism the guide-bars are pivoted at their front ends to the platform and are movable at their rear ends toward and from the binder-deck and are held in their operative position by the shifting arms, which connect the rear ends of ythe guide-bars through intermediate parts ICO IIO

with the needle, whereby a very strong and rigid support for the guide-bars is secured.

O represents the uprightshaft of the knetter mechanism, which is journaled in a standard o', arranged opposite the binder-deck on the grainward side thereof.

P represents the breastplate, which is arranged opposite the binder-needle and provided on its central part with two outwardlyprojecting arms p p, which are mounted loosely on the upper end of the knotter-shaft. The front end of the breastplate is secured to an upright supporting-rod p', which is arranged with its upper part parallel with the knetter-shaft and which inclines with its lower part toward the standard 0 and is secured to a lug thereon by a bolt Q32, as shown in Fig. l.

For the purpose of adjusting vthe knetter mechanism to the binder-needle, the breastplate carrying the binder mechanism is turned on the knetter-shaft so as to move its front part toward and from the deck. In order to effect this adjustment without straining any of the parts, the following device is provided:

Q represents an adjusting-arm secured at its front end to the supporting-mdp' below the breastplate and provided at its rear end with a semicircular socket Q, which fit-s concentrically against the circular rear or outer side of the standard o' below the knotter mechanism, as shown in Figs. l, 2, 3, and 7.

Q is an adjusting-rod which is connected at its rear end to an inwardly-projectinglug Q2, arranged on the standard o', and which passes with its screwthreaded front end through an'eye Q3 on the inner side of the adjusting-arm Q.

QL Q5 are screw-nuts arranged on the adj usting-rod in front and in rear of the eye Q3.

Upon loosening the rear nut Q4 and tightening the front nut the adjusting-arm is swung inwardly in the direction of the arrow, Fig. 3, whereby the breastplate is moved toward the deck. Upon loosening the front nut Q5 and tightening the rear nut Q4 the adjustingarm is swung outwardly and the breastplate is moved away from the deck. While moving the adjusting-arm inwardly or outwardly it turns concentrically with the knotter-shaft, on which the breastplate is mounted loosely, whereby these parts are' not strained, which otherwise would be the case if the breastplate and the adjusting-arm were pivoted on different centers. The breastplate is held in its adjusted position by a bolt Q6, passing through a lug Q7 on the outer side of the standard 0', and a concentric slot Q8, formed in a lug Q9, which latter projects outwardly from the adjusting-arm, as shown'in Figs. l, 2, 3, and 7.

The mechanism for driving the binding mechanism is constructed as follows:

R represents a gear-wheel mounted loosely on the lower end of the conveyer-shaft je or some other shaft having the same speed. This etreis gear-wheel has twelve teeth and meshes with a gear-pinion r, having nine teeth, so that the relation of these gears is three rotations Vof the wheel to four rotations ot' the pinion. The gear-pinion is secured to the upper end ot' a short counter-shaft r', which is journaled in a stationary bearing.

s is a sprocket-chain which passes around a sprocket-pinion s' on the lower end of the counter-shaft r anda sprocket-wheel s2 on the lower end of the knotter-shaft O. The sprocket pinion has six teeth and the sprocket-wheel twenty-four teeth, so that the relationof these sprocket-wheels is four rota; tions of the pinion to one rotation of the wheel. knotter-shaft O and sprocket-wheel s2 make one rotation, the sprocket-pinion s and gearpinion r' four rotations, and the gear-wheel E three rotations. The binder-needle is oscillated by means of a rod s?, connected at one end to a rock-arm s4 on the lower end of the needle rock-shaft M and with its other end to a crank S5 on the sprocket-wheel s2, the distance from the crank S5 to the center of the sprocket-wheel s2 being less than the length of the rock-arm s4, so that a rotary.

movement of the crank imparts a rocking movement to the needle.

T represents a coupling orclutch dog which is pivoted on the gear-wheelR so as to swing laterally thereon and which is provided with an inner coupling shoulder or face t and an outer uncoupling or trip face t..

152152 are two driving-arms secured to diametrically-opposite sides of the shaft j and each provided with a depending coupling roller or lug t3. When the machine is in operation, the shaft j and its driving-arms rotate constantly. When the binder mechanism is not in operation, the coupling-dog is moved inwardly into the position shown in Fig. 8, in which position the coupling-shoulder t of the dog is arranged inside of the path of the drivinglugs on the driving-arms, and the latter therefore turn without operating the binder mechanism. Upon moving. the

coupling-dog outwardly, so that its couplingshoulder stands in the path of the driving- During each binding operation the IIO dogs, one of the latter engages this shoulder,

as shown in Fig. 9, and so couples the gearwheel R with the shaft ,7'6 and sets the binder mechanism in motion. The outward movement of the coupling-dog when released is effected by a spring t4. While the binder mechanism is inoperative and the stalks are being collected on the binder-deck, the coupling-dog is held in its inner or backward position, so that the driving-lugs clear the same, by the inner arm u of a trip-lever U. This lever is pivoted on the adjacent stationary part of the machine and has a bifurcated outer arm u', which has a shoulder or abutment u2 on one side and a transverse pin a3 on the opposite side.

a4 is an upright compressor-shaft j ournaled in rear of the deck and provided with one or more compressor-arms a5, against which the stalks are piled or gathered by the conveyer.

u is an actuating bar or rod connected at one end to a rock-arm 167 on the compressorshaft and provided in its opposite end with a longitudinal slot u8, which receives the pin us in the bifurcated outer arm it of the triplever.

V represents a rock-lever pivoted to the frame above the sprocket-wheel s2 and provided with a roller or projection fu, which engages with a compressor-operating cam e', formed in the upper side of the sprocketwh eel si. This lever is connected with a rockarm c2 on the compressor-shaft by an elastic connecting-rod W, which permits the compressor-shaft and connecting parts to have a slight movement independent of the compressor-cam for tripping the clutch that couples the binder mechanism with the driving mechanism, but which permits of transmitting the movement of the compressor-cam to the compressor shaft and arms for releasing the bundle after being tied. This elastic link consists, essentially, of an open frame w, pivoted at one end to the rock-lever V, a rod w', connected at one end with the rock-arm o2 and sliding with its other end through an eye wi on the adjacent end of the yoke, and a spring w3 interposed between said eye and a collar or shoulder fw4 on the rod w'.

Vhile the binder mechanism is inoperative and the stalks are being gathered on the deck to form a bundle the parts of the binder mechanism are in the position shown in Figs. 1, 2, 3, 5, 8, and l0, in which position the couplingdog is held out of engagement with the driving-lugs by the trip-lever. The compressorshaft is turned so that the compressor-arms proJect across the stalk throat or passage, and the actuating-bar engages the inner end of its slot with the pin its, and its inner end stands opposite the shoulder u2. When a sufcient number of stalks have been delivered by the conveyers against the compressorarms, so that the latter yield backwardly and turn the compressor-shaft slightly in the direction of the arrow, Fig. 8, the actuating-bar is moved inwardly. During this inward movement of the bar its inner end by engaging with the shoulder u2 on the outer arm of the trip-lever turns the latter so that its inner arm is disengaged from the couplingdog. The instant the latter is released it is moved outwardly by its spring, so that its driving-shoulder stands in the path of the driving-lugs and is engaged by one of the same,thereby coupling the binder mechanism with the driving mechanism. Vhen the compressor arms and shaft are turned by the pressure of the accumulated stalks for disengaging the trip-lever from the couplingdog, the driving mechanism of the needle and the knetter mechanism remain stationary. The instant the dog is coupled with the driving-shaft the train of gearing begins its cycle of movement for operating the binder mechanism. During the first half-turn of the sprocket-Wheel s2 its crank S5 moves the needle forward, and during the second halfturn the needle is moved backward. The compressor-cam is so constructed that it holds the compressorarms across the stalk-passage until the binding operation is completed, then turns the compressor-shaft and its compressor-arms, so as to permit of discharging the bundle from the deck by means of the discharge -arms n2 on the knotter-shaft,and then turns this shaft at the end of the rotation of the sprocket-wheel s2, so that the compressorarms project across the stalk-passage preparatory to receiving the next bundle. When the compressor-shaft is turned for discharging the bundle, the inner end of the actuating-bar u clears the shoulder u2 of the triplever and slides idly with its slot along the pin Los of the same, as shown in Fig. 9, thereby avoiding an excessive movement of the tri p-lever. When the compressor-cam turns the compressor-shaft for restoring the compresser-arms, the actuating-bar slides outward idly until the inner end of its slot engages With the pin a3 of the trip-lever. The latter now moves with the actuating-bar to the end of its outward movement, and is turned thereby, so that its inner arm stands in the path of the trip-face of the couplingdog. As the latter rotates it engages with the trip-lever and is thereby turned inwardly until its coupling-shoulder t is disengaged from the driving-lug, when the movement of the binder mechanism ceases. During the last portion of the outward movement of the actuating-bar it swings on the pin a3 as a pivot, and its inner end is carried opposite the shoulder u2 of the trip-lever preparatory to engaging the same during the next inward movement of the actuating-bar.

Inasmuch as it requires three turns of the gear-wheel R in order to complete the cycle of operations of the binder mechanism, it is necessary to keep the inner arm u of the triplever out of the path of the coupling-dog until these operations have been completed. For this purpose the gear-pinion r' is provided with a shifting lug or tappet which is adapted to engage with the inner arm u of the trip-lever. This tappet is so arranged that it engages with the trip-lever and shifts the saine ont of the path of the coupling-dog during three turns of the gear-pinion, but leaves the trip-lever standing in the path of said dog at the end of the fourth turn, which is at the end of the binding operation, to permit the binder mechanism to be uncoupled from the driving mechanism. In the uncoupled position of the coupling-dog the shifting tappet stands close to the inner side of the inner arm of the trip-lever. If the trip-lever tends to drop back into its operative position after being released from the dog, the shifting tappet at the end of its first turn engages with the trip-lever and moves the same out of the path of the dog just be- IOG fore the latterv reaches the trip-lever, and this ficiently to clear the coupling-dog; but at the end of the fourth turn the gear-pinion gains one complete turn and comes around to the starting-point with reference' to the gear- Wheel, in which position of the pinion its shifting tappet misses or does not reach the 'trip-lever in time to deflect it out of the path of the couplingdog, thereby causing the binder mechanism to be uncoupled from the driving mechanism. If the shaft from which the binder mechanism is driven has a different speed, the relative size of the gear-wheels must be changed accordingly.

This construction of the actuating mechanisfm of the self-binder is very compact and can. therefore be placed higher up in the machine, where the available space is limited, than the mechanism heretofore employed. This avoids interference of the mechanism with the ground and greatly reduces the liability of the mechanism becoming clogged with foreign matter.
